Hi All, I'm integrating a Boost.Python module into a Django project. I'm getting spammed with warnings for duplicate conversion methods. Django uses a multi-process model that loads separate copies of the python module into memory. The module does fine with multiprocess initialization. The warnings occur when, somehow, Django calls __init__ a second time on my module, within the same process. The warnings look like: C:\work\svn\sw\branches\python\imager\__init__.py:1: RuntimeWarning: to-Python converter for class std::vector<class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >,class std::allocator<class basic_string<char,struct std::char_traits<char>,class std::allocator<char> > > > already registered; second conversion method ignored. I have a few questions about this, as I am new to python. I thought that modules were supposed to be process-global. How do i enforce this and prevent __init__ from being called twice? Are the warnings benign? Should I be concerned about the state of my library static globals (ie is the compiled code going through a second initialization process)?
